{"version":"1.0","type":"rich","title":"Task2Q1","description":"This example uses a stacked bar chart to compare performance metrics (horsepower, torque, and highway MPG) across seven car makes from a CSV file. Built with D3 v7, it loads data via `d3.csv`, formats values with `d3.format`, and renders SVG bars using `d3.scaleBand` for the y-axis and `d3.scaleLinear` for the x-axis. Segments are colored via `d3.scaleOrdinal`, and interactive tooltips reveal exact values on hover using D3's event handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ef831f95ce8d4df79935b2dc6c8aa13c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
